Normal working and installation conditions2.1 Ambient temperature: -5oC~+40oC, the average temperature shall not exceed 35oin 24 hours2.2 Altitude: shall not exceed 2,000m2.3 Pollution condition: grade 32.4 Humidity: the relative humidity shall not exceed 50% when the environmental temperature is +40oC in installing place. And the relative humidity maybe higher at the lower temperature condition, the maximum humidity can up to 90%at +20oC2.5 The product shall be installed in the place without rain and snow, without remarkable shake and quiver2.6 The switch shall be installed vertically3. Structure and featuresThe switch is consisted of underpan, base, cover, handle and shield.
